全固态锂电池用新型复合固态电解质PEO/Li6.10Zr0.10P0.90S5Cl
A New Composite Solid Electrolyte PEO/Li6.10Zr0.10P0.90S5Cl for All-solid-state Lithium Battery
摘要
Abstract
In order to improve the room temperature conductivity and the performance in restraining the growth of lithium dendrites of polyethylene oxide(PEO),ZrCl4 doping modification method was used to improve the structural stability of sulfide electrolyte as active filler in PEO matrix.The sulfide material Li6.10Zr0.10P0.90S5Cl(LPSC-10)with ionic conductivity up to 1.90 mS/cm was optimized and selected as the filler for All-solid-state lithium battery(ASSLBs).The results show that the PEO-based solid electrolyte has excellent properties,including high ionic conductivity(0.44 mS/cm,60℃),moderate Young's modulus(13.7 MPa)and excellent interfacial stability.The Li|Li(0.1 mA/cm2 for 600 h)and LiILiFePO4 batteries at 60℃(capacity maintained at 99.2％after 200 cycles at 2C)have excellent cycle stability.This work is expected to promote the development of ASSLBs with high electrochemical performance and provide reference information for the further development of battery technology of the rocket and others.关键词
